DETAILED DESCRIPTION
[0062] FIG. 1 illustrates an example of a method 100.
[0063] In examples, the method 100 can be performed by any suitable
apparatus 10. For example, any suitable apparatus 10 comprising
means for performing the method 100 and/or means configured to
perform the method 100.
[0064] In examples, the method 100 can be performed by an apparatus
10 as described in relation to, at least, FIG. 6A and/or FIG.
6B.
[0065] In some examples, the method 100 can be performed by an
apparatus 10 as described in relation to, at least, FIGS. 6A and/or
6B, in any suitable electronic device.
[0066] One or more of the features discussed in relation to FIGS. 1
and/or 2 can be found in one or more of the other figures.
[0067] At block 102, the method comprises causing display of at
least one world-locked volumetric object 12 having at least one
non-viewable region 14.
[0068] In some examples, the non-viewable region 14 comprises a
static and/or animated non-viewable region 14.
[0069] In some examples, the non-viewable region 14 can be
considered to be a static and/or animated non-viewable region
14.
[0070] In examples, causing display of the at least one
world-locked volumetric object 12 can be considered controlling
display of the at least one world-locked volumetric object and/or
rendering the at least one world-locked volumetric object 12.
[0071] In general, as used herein, `causing an action or actions`
is intended to also disclose performing the action or actions.
[0072] For example, causing display of the at least one
world-locked volumetric object 12 is also intended to disclose
displaying the at least one world-locked volumetric object 12.
[0073] Any suitable method for causing display of at least one
world-locked volumetric object 12 having at least one non-viewable
region 14, such as a static and/or animated non-viewable region 14
can be used.
[0074] For example, an apparatus 10 as described in relation to
FIG. 6A and/or as described herein can be used to control at least
one display to display at least one world-locked volumetric object
12 having at least one non-viewable region 14.
[0075] In examples, a volumetric object 12 can be considered an
object having a volume.
[0076] In examples, a volumetric object 12 can be considered to be
an object having a height, a width, and a length.
[0077] In some examples, a volumetric object 12 can be considered a
visual representation of an object in three physical
dimensions.
[0078] In examples, a volumetric object 12 can be considered a
three-dimensional object or 3D object.
[0079] In examples, the volumetric object 12 can be considered a
virtual object and can be computer generated and/or an image of a
real-world object, in real space, that is live or recorded.
[0080] In examples, the volumetric object 12 can be a computer
generated or synthesized object and/or data recorded of a
real-world object, that is an object that exists in the real
world.
[0081] For example, the at least one volumetric object 12 can be a
representation of a real-world object that has been captured for
display as a virtual volumetric object 12.
[0082] In examples, any suitable combination of capturing/recording
and synthesizing of at least one volumetric object 12 can be
used.
[0083] Any suitable type and/or sort and/or form of volumetric
object(s) 12 can be used. For example, a volumetric object can be
or comprise at least one polyhedron, and/or at least one
triangulated polyhedron, and/or at least one tetrahedron, and/or at
least one polygon, and/or at least one point cloud, point cloud
coded objects (PCC ISO/IEC JTC 1/SC 29/WG 11 MPEG-I Part 5), 3G
graphics and so on.
[0084] In some, but not necessarily all, examples the at least one
volumetric object 12 can comprise one or more textures, and/or
lighting, and/or one or more bump maps, and/or one or more solids
and/or one or more shells and so on.
[0085] In examples, the at least one volumetric object 12 can be
considered to be world-locked when the location or position and
orientation of the object is determined relative to its surrounding
environment or world. For example, a world-locked volumetric object
12 can be fixed at a location or position and orientation relative
to its surrounding environment or world.
[0086] In some examples, the location or position and/or
orientation of a world-locked volumetric object 12 can change or
vary relative to its surrounding environment or world. For example,
a world-locked volumetric object 12 can be configured to move/can
move through its environment or world, independent of a viewing
position 16 of a user.
[0087] In examples, the at least one world-locked volumetric object
12 can be caused to be displayed and/or displayed in any suitable
environment.
[0088] For example, the environment can be an augmented reality in
which a user experiences a partially artificial environment, or
virtual space, as a virtual scene comprising a real scene, for
example a real visual scene, of a physical real environment, or
real space, supplemented by one or more visual elements, such as
one or more volumetric objects 12, rendered, or caused to be
displayed, by an apparatus to a user.
[0089] In examples, augmented reality can be considered mixed
reality or hybrid reality.
[0090] In some examples, the at least one world-locked volumetric
object 12 can be caused to be displayed in a virtual reality
environment. A virtual reality environment can be considered to be
an environment in which a user experiences a fully artificial
environment, or a virtual visual space, as a virtual scene,
comprising one or more visual elements, such as one or more
volumetric objects 12, rendered, or caused to be displayed, by an
apparatus to a user.
[0091] In examples, the at least one world-locked volumetric object
12 can be considered to have at least one static and/or animated
non-viewable region 14.
[0092] In examples, a static object or portion can be considered an
object or portion of an object that has no animation and/or a
single temporal frame.
[0093] In examples, an animated object or portion can be considered
an object or portion of an object that is animated or comprises a
visual object sequence comprising two or more temporal frames.
[0094] A static non-viewable region can be considered a static
region of the world-locked volumetric object 12 that is
non-viewable.
[0095] In examples, a static non-viewable region can be considered
a static region that cannot be displayed and/or rendered.
[0096] For example, a static volumetric representation of a
person's head can have display data missing for the back region of
the head. In such an example, the back of the user's head, or the
back of the volumetric object 12, can be considered a static
non-viewable region 14.
[0097] An animated non-viewable region 14 can be considered an
animated region of the world-locked volumetric object 12 that is
non-viewable.
[0098] In examples, an animated non-viewable region can be
considered an animated region that cannot be displayed and/or
rendered.
[0099] For example, an animated volumetric representation of a
person's head can have display data missing for one or more sides
and/or aspects.
[0100] In examples the animation can be the user shaking their
head. In examples, the animation can be recorded or captured from
the front, but not from the other sides or aspects of the user's
head. In such an example, the sides and back of the user's head, or
the sides and back of the volumetric object 12, can be considered
an animated non-viewable region 14.
[0101] In examples, a static and/or animated non-viewable region 14
can be considered at least one static and/or animated non-viewable
area and/or facet and/or part and/or portion and/or face and/or
side and/or feature and so on.
[0102] In examples, it can be considered that the at least one
world-locked volumetric object 12 has at least one region and/or
facet and/or part and/or portion and/or face and/or side and/or
feature and so on that cannot be displayed or cannot be displayed
with sufficient quality, for example resolution.
[0103] In examples, the at least one world-locked volumetric object
12 comprises missing static and/or animated display data and/or
static and/or animated display data at sufficient quality.
[0104] In examples, the missing static and/or animated display data
has not been captured or has not been synthesized; or the missing
static and/or animated display data has not been received or has
not been retrieved.
[0105] For example, the at least one world-locked volumetric object
12 can have at least one region, for example at least one side,
which has not been captured, in relation to real-world objects or
regions, or has not been synthesized, in relation to computer
generated objects or regions.
[0106] Accordingly, such regions of such a volumetric object 12 can
be considered non-viewable and/or non-displayable.
[0107] In examples, missing static and/or animated display data may
exist but has not yet been received, for example, from at least one
remote source, or has not yet been retrieved from, for example, at
least one memory.
[0108] In examples, the missing data can be one or more missing
points, and/or one or more missing vertexes, and/or one or more
missing triangles, and/or one or more missing solids, and/or one or
more missing shells, and/or one or more missing textures, and/or
one or more missing bump maps, and/or one or more missing meshes,
and/or missing lighting information, and/or any data or information
that is needed to represent some visual aspect of the at least one
volumetric object 12. In some examples this information is
available but not at sufficient quality (for example lower quality
texture).
[0109] For example, a user's head may have been captured from the
front side, right side and back side, but not from the left side.
Accordingly, the user's head, displayed as a volumetric object 12,
could not be viewed from the left side meaning that such a
volumetric object 12 has a static non-viewable region 14.
[0110] Similarly, a user's head may have been completely captured
from all sides, but an animated sequence of the user's head
captured from the front side but not the other sides.
[0111] Accordingly, such a volumetric object 12 has animated
non-viewable regions 14 as the generation of the user's head
shaking is viewable from the front side but not the left, back or
right sides.
[0112] In examples, the at least one volumetric object 12 can be
considered at least one partial volumetric object 12. For example,
a shell object that is not manifold.
[0113] At block 104 the method 100 comprises determining a change
in a user's viewing position 16 relative to the at least one
world-locked volumetric object 12.
[0114] In examples, movement can comprise any suitable rotation
and/or translation of the user relative to the at least one
world-locked volumetric object 12.
[0115] Any suitable method for determining a change in a user's
viewing position 16 relative to the at least one world-locked
volumetric object 12 can be used.
[0116] In examples, the change in the user's viewing position 16
relative to the at least one world-locked volumetric object 12 can
be due to a change user's viewing position 16 and/or a change in
the position of the volumetric object 12.
[0117] In examples, a change in the user's viewing position 16 can
be caused, at least in part, by one or more user inputs. In
examples, any suitable user input can be used.
[0118] For example, one or more user inputs made via one or more
user input devices can cause a change in a user's viewing position
16. For example, this can occur in virtual reality examples.
[0119] Additionally, or alternatively, a change in a user's
real-world position can cause a change in a user's viewing position
16. For example, in augmented reality examples.
[0120] That is, in examples, a user's movement in a real-world
environment can cause movement of the user's viewing position 16
relative to the at least one world-locked volumetric object 12.
[0121] For example, a user may walk through a real-world
environment, such as a park, having at least one world-locked
volumetric object 12 overlaid thereon and the user's movement in
the real-world can cause a change of the user's viewing position
relative to the at least one world-locked volumetric object 12.
[0122] In some examples, determining a change in a user's viewing
position 16 relative to the at least one world-locked volumetric
object 12 comprises estimating a future viewing position of the
user relative to at least one world-locked volumetric object
12.
[0123] Any suitable method for estimating a future viewing position
of the user relative to the at least one world-locked volumetric
object 12 can be used.
[0124] For example, a user's trajectory can be tracked and from
this an estimation of the user's viewing position/location in the
future can be estimated. Any suitable trajectory estimation method
or methods can be used.
[0125] Motion of the user's viewing position 16 can have any
suitable number of degrees of freedom. For example, motion of the
user's viewing position 16 can have any suitable rotation and/or
translation and can, in examples, be moved with six degrees of
freedom.
[0126] In examples, determining a change in the user's viewing
position 16 relative to the at least one world-locked volumetric
object 12 can comprise determining a user input that will change a
user's viewing position 16 relative to the at least one
world-locked volumetric object 12.
[0127] In examples, determining if the change in the user's viewing
position 16 relative to the at least one world-locked volumetric
object 12 will cause display of at least a portion of the at least
one non-viewable region 14 of the at least one world-locked
volumetric object 12 can be considered to comprise determining if a
user input will cause a change in the user's viewing position 16
relative to the at least one world-locked volumetric object 12
which will cause display of at least a portion of the at least one
non-viewable region 14 of the at least one world-locked volumetric
object 12.
[0128] At block 106, the method comprises determining if the change
in the user's viewing position 16 relative to the at least one
world-locked volumetric object 12 will cause display of at least a
portion of the at least one non-viewable region 14 of the at least
one world-locked volumetric object 12.
[0129] Any suitable method for determining if the change in the
user's viewing position 16 relative to the at least one
world-locked volumetric object 12 will cause display of at least a
portion of the at least one non-viewable region 14 of the at least
one world-locked volumetric object 12 can be used.
[0130] In examples, determining if the change in the user's viewing
position 16 relative to the at least one world-locked volumetric
object 12 will cause display of at least a portion of the at least
one non-viewable region 14 of the at least one world-locked
volumetric object 12 comprises at least one of: accessing metadata
of the at least one world-locked volumetric object 12, analyzing
the at least one world-locked volumetric object 12 and accessing
capture or synthesized information of the at least one world-locked
volumetric object 12.
[0131] For example, metadata of the at least one world-locked
volumetric object 12 can be accessed to determine that the
determined change in the user's viewing position 16 relative to the
at least one world-locked volumetric object 12 will cause a
non-viewable region 14 of the volumetric object 12 to be brought
into view.
[0132] Similarly, capture or synthesizing information of the at
least one world-locked volumetric object 12 can be accessed to
determine that a non-viewable region 14 of the volumetric object 12
will be brought into view by the determined change in the user's
viewing position 16 relative to the volumetric object 12.
[0133] Additionally, or alternatively, the volumetric object 12 can
be analyzed to make the determination.
[0134] In examples, a future viewing position of the user relative
to the at least one world-locked volumetric object 12 is estimated,
the estimated trajectory of the user can be analyzed and it can be
determined that the estimated trajectory will cause a non-viewable
region 14 of the at least one world-locked volumetric object 12 to
be displayed.
[0135] If it is determined that the change in the user's viewing
position 16 will cause display of at least a portion of the at
least one non-viewable region 14, the method proceeds to block
108.
[0136] At block 108, the method 100 comprises causing the at least
one world-locked volumetric object 12 to be user-locked.
[0137] In examples, a user-locked volumetric object 12 can be
considered to be in some way or regard locked to a position or
viewing position 16 of the user.
[0138] In examples, motion of a user-locked volumetric object 12 is
linked to and/or relative to and/or dependent on motion of a user's
viewing position 16.
[0139] In some examples, a user-locked volumetric object 12 is
moved relative to movement of a user's viewing position 16 so that
the user-locked volumetric object 12 appears fixed in position
relative to the user under movement of the user's viewing position
16.
[0140] In examples, causing at least one world-locked volumetric
object 12 to be user-locked, or to become a user-locked volumetric
object 12, can be considered causing movement of the at least one
user-locked volumetric object 12 relative to motion of the user's
viewing position 16 to prevent display of at least one non-viewable
region 14 of the volumetric object 12.
[0141] In examples any suitable rotation and/or translation of the
at least one user-locked volumetric object 12 can be used.
[0142] Consequently, FIG. 1 illustrates a method comprising:
[0143] causing display of at least one world-locked volumetric
object 12 having at least one non-viewable region 14;
[0144] determining a change in a user's viewing position 16
relative to the at least one world-locked volumetric object 12;
[0145] determining if the change in the user's viewing position 16
relative to the at least one world-locked volumetric object 12 will
cause display of at least a portion of the at least one
non-viewable region 14 of the at least one world-locked volumetric
object 12; and
[0146] if it is determined that the change in the user's viewing
position 16 will cause display of at least a portion of the at
least one non-viewable region 14, causing the at least one
world-locked volumetric object 12 to be user-locked.
[0147] If it is determined at block 106 that the change in the
user's viewing position 16 will not cause display of at least a
portion of the at least one non-viewable region 14 the method
returns to block 102.
[0148] The method 100 is advantageous as, for example, it provides
for allowing user viewing motion with, for example, six degrees of
freedom in relation to volumetric objects 12 even if they are not
fully viewable, that is viewable from a subset of possible user
viewing positions 16.
[0149] Additionally, or alternatively, the method 100 provides for
improved display of volumetric objects 12 that are fully viewable
when static but viewable from a subset of viewing positions 16 with
regard to one or more animations of the volumetric object 12.
[0150] This can, for example, enable the use of animations, such as
gestures, that otherwise would be non-usable or potentially could
prevent using a captured model as a whole.
[0151] Additionally, or alternatively, partially incomplete
three-dimensional captures can be used in viewing scenarios
providing six degrees of freedom with regard to movement of a
user's viewing position 16. This can significantly increase the
content that can be made compatible with six degree of freedom
viewing.
[0152] In examples, one or more of the actions of the method 100
can be reordered and/or omitted. In some examples, the method 100
comprises one or more further actions. This is illustrated in the
example of FIG. 1 by the method proceeding to point A. See, for
example, FIG. 2.
[0153] FIG. 2 illustrates an example of a method 100.
[0154] In the example of FIG. 2, the method 100 proceeds from point
A in the example of FIG. 1.
[0155] In the example of FIG. 2, the at least one user-locked
volumetric object 12 has at least one animated non-viewable region
14.
[0156] At block 110, the method 100 comprises determining that an
animation 18 of the at least one user-locked volumetric object 12
has finished.
[0157] Any suitable method for determining that an animation of the
at least one user-locked volumetric object 12 has finished can be
used. For example, it can be determined that the frames of the
animation have been exhausted and/or a time period for causing
display of the animation has expired.
[0158] At block 112, the method 100 comprises in response to
determining that the animation 18 of the at least one user-locked
volumetric object 12 has finished, causing the at least one
user-locked volumetric object 12 to be world-locked.
[0159] This is also advantageous as, for example, it allows a
volumetric object 12, having an animation viewable from a subset of
viewing position, to be used with six degrees of freedom motion of
a user's viewing position 16 relative to the volumetric object
12.
[0160] Accordingly, in examples where the at least one user-locked
volumetric object 12 has at least one animated non-viewable region
14 the method 100 can comprise:
[0161] determining that an animation 18 of the at least one
user-locked volumetric object 12 has finished; and
[0162] in response to determining that the animation 18 of the at
least one user-locked volumetric object 12 has finished, cause the
at least one user-locked volumetric object 12 to be
world-locked.
[0163] See, for example, FIGS. 5A to 5C.
[0164] In some examples, for example FIG. 1 and/or FIG. 2, the
method 100 comprises: determining a change in a user's viewing
position 16 relative to the at least one world-locked volumetric
object 12, from a viewing position of a non-viewable animated
region of the at least one world-locked volumetric object 12 to a
viewing position of a viewable animated region of the at least one
world-locked volumetric object 12; and
[0165] in response to determining the change in the user's viewing
position 16 to a viewing position of a viewable animated region of
the at least one world-locked volumetric object 12, causing display
of an animation of the at least one world-locked volumetric object
12.
[0166] For example, the method 100 can comprise determining that
the user's viewing position 16 has moved to a point where an
animation of the volumetric object 12 can be displayed and, in
response, causing display of the animation.
[0167] Any suitable method for determining a change in the user's
viewing position can be used, see, for example, block 104 of FIG. 1
and the associated description.
[0168] In examples, determining a change in the user's viewing
position 16 relative to the at least one world-locked volumetric
object 12, from a viewing position of an animated non-viewable
region 14 of the at least one world-locked volumetric object 12 to
a viewing position 16 of a viewable animated region of the at least
one world-locked volumetric object 12, comprises estimating a
future viewing position of the user relative to the at least one
world-locked volumetric object 12.
[0169] Any suitable method for estimating a future viewing position
16 of the user relative to the at least one world-locked volumetric
object 12 can be used, see, for example, block 104 of FIG. 1 and
the associated description.
[0170] In examples, a user's trajectory may be estimated for a
future predetermined amount of time, such as a predetermined number
of seconds. In examples, any suitable length of time can be used.
For example, a length of time in the range 3 seconds to 15 seconds,
and/or in the range 5 seconds to 10 seconds.
[0171] In examples, it can be estimated that the user's viewing
position 16 will provide a view of a viewable animated region of
the object 14 for the determined amount of time in which case the
animation 18 can be triggered. However, if it is determined from
the estimated trajectory of the user's viewing position 16 that the
user's viewing position 16 will cause display of an animated
non-viewable region 14, the animation 18 will not be triggered.
[0172] FIG. 3 illustrates an example of object display.
[0173] In the example of FIG. 3 a top down view of a world-locked
volumetric object 12 is shown. This is indicated by the coordinates
in the lower right of FIG. 3 showing the x and y coordinates whole
looking straight down the z axis.
[0174] In the example of FIG. 3, for the purpose of illustration,
the world-locked volumetric object 12 is a cube. A perspective view
of the volumetric object 12 is shown in the lower left corner of
FIG. 3. The corresponding x, y and z axis is also shown.
[0175] In the example of FIG. 3, the volumetric object 12 is
world-locked at a particular value of x, y and z, and having a
fixed orientation.
[0176] The world-locked volumetric object 12 has six faces. In the
example of FIG. 3 a first face 17A can be considered a front face,
a second face 17B can be considered a left face, a third face 17C
can be considered a back face, a fourth face 17D can be considered
a right face, fifth face 17E can be considered a top face and a
sixth face 17F can be considered a bottom face.
[0177] The faces are also indicated on the perspective view of the
volumetric object 12 in the lower left corner of FIG. 3.
[0178] Also illustrated in the example of FIG. 3 are four user
viewing positions 16A, towards the front face 17A, 16B, towards the
left face 17B, 16C, towards the back face 17C and 16D, towards the
right face 17D.
[0179] In the example of FIG. 3, the user's viewing position 16 can
move with six degrees of freedom, however, for the purpose of
illustration, the viewing positions 16A, 16B, 16C, 16D are
considered.
[0180] In the example of FIG. 3 the volumetric object 12 has a
static non-viewable region 14 towards the left face 17B.
[0181] In the example of FIG. 3, the data for displaying the left
face 17B is missing, and therefore the left face 17B of the
volumetric object 12 cannot be displayed or caused to be
displayed.
[0182] Accordingly, in the example of FIG. 3, if the user's viewing
position 16 starts at viewing position 16A and moves towards
viewing position 16D the volumetric object 12 can be displayed or
caused to be displayed correctly and therefore remains world-locked
and does not move relative to the user's viewing position
movement.
[0183] Similarly, as the user's viewing position 16 moves from
viewing position 16D to 16C, as indicated by the arrows, the
volumetric object 12 can be correctly displayed and therefore the
volumetric object 12 remains world-locked.
[0184] However, as the user's viewing position 16, moves from
viewing position 16C towards 16B, it is determined that the change
in the user's viewing position 16 relative to the world-locked
volumetric object 12 will cause display of the static non-viewable
region 14, which in this example is the left face or side 17B.
[0185] Accordingly, as the user's viewing position 16 moves from
viewing position 16C towards viewing position 16B the volumetric
object 12 becomes user-locked and rotates with the movement of the
user's viewing position 16 so that face 17C remains viewable by the
user. See, for example, FIGS. 4A to 4C.
[0186] In examples, when the volumetric object 12 has become
user-locked, it can be "reset" if the user's viewing position 16
moves such that the volumetric object 12 is no longer in the user's
view and the volumetric object 12 can be returned to being
world-locked.
[0187] In the example of FIG. 3, the volumetric object 12 has an
associated animation 18. This is illustrated by the bold
double-headed arrow near the back face 17c.
[0188] If the example of the volumetric object 12 is a person's
head, the animation 18 could be a shaking or other motion of the
head.
[0189] In the example of FIG. 3, the volumetric object 12 has a
plurality of animated non-viewable regions 14 (not indicated in the
example of FIG. 3 for purposes of clarity). That is because, in the
example of FIG. 3, the animation 18 is viewable from viewing
positions towards the back face 17C, for example viewing position
16C.
[0190] Accordingly, in the example of FIG. 3, faces 17A, 17B, 17D,
17E and 17F are animated non-viewable regions 14.
[0191] In the example of FIG. 3, if the animation 18 is active when
the user is at viewing position 16C, the volumetric object 12 will
become user-locked if the user moves away from viewing position 16C
towards viewing position 16B or viewing position 16D to avoid the
animated non-viewable regions 14 from being displayed or caused to
be displayed.
[0192] However, once the animation 18 has completed, the volumetric
object 12 can be returned to being world-locked. See, for example,
FIGS. 5A to 5C.
[0193] In the example of FIG. 3, if the user is viewing from
viewing position 16D and moves to viewing position 16C it can be
determined that the animation is available from this viewing
position and then animation 18 can be triggered.
[0194] FIGS. 4A to 4C show examples of object display.
[0195] In the examples of FIGS. 4A to 4C a top down view of a
volumetric object 12 is shown, similarly to the example of FIG.
3.
[0196] In the examples of FIGS. 4A to 4C the volumetric object 12
is again a cube.
[0197] Similarly to the example of FIG. 3 the volumetric object 12,
in the examples of FIGS. 4A to 4C, has a static non-viewable region
14 towards the left face 17B.
[0198] In the example of FIG. 4A, the user's viewing position 16 is
towards the front face 17A and the volumetric object 12 is
world-locked.
[0199] As shown in the example of FIG. 4B, the user changes the
viewing position 16 around towards viewing position 16B in FIG.
3.
[0200] It is determined that the user's change in viewing position
16 would cause display of at least a portion of the static
non-viewable region 14 and therefore the volumetric object 12
becomes user-locked and rotates with the movement of the user's
viewing position 16 so that face 17A remains viewable to the user
as the user's viewing position 16 moves to corresponding viewing
position 16B of FIG. 3. This is shown in FIGS. 4B and 4C.
[0201] The user's previous viewing positions are shown in dashed
lines.
[0202] FIGS. 5A to 5C show examples of object display.
[0203] The examples of FIGS. 5A to 5C are similar to those shown in
FIGS. 4A to 4C.
[0204] However, in the example of FIG. 5A, the volumetric object 12
has an animation 18 and the user is viewing the volumetric object
12 from corresponding viewing position 16C towards the back face
17C of the volumetric object 12.
[0205] In FIG. 5B, the user's viewing position moves towards
corresponding viewing position 16D and therefore towards an
animated non-viewable region 14. The volumetric object 12 is
therefore caused to become user-locked and rotates with the
movement of the user's viewing position 16 to keep the animation 18
visible to the user.
[0206] However, in the example of FIG. 5B, the animation 18
finishes and therefore the volumetric object 12 is returned to
being world-locked.
[0207] Accordingly, in the example of FIG. 5C, as the user moves to
corresponding viewing position 16D of FIG. 3, the volumetric object
12 no longer rotates with the movement of the user's viewing
position 16.
[0208] Object display as described herein is advantageous as, for
example, it provides for allowing user viewing motion with, for
example, six degrees of freedom in relation to incomplete
volumetric objects 12.
[0209] Additionally, or alternatively, the method 100 provides for
improved display of volumetric objects 12 that are fully viewable
when static but viewable from a subset of viewing positions 16 with
regard to one or more animations of the volumetric object 12.
[0210] This can, for example, enable the use of animations, such as
gestures, that otherwise would be non-usable or potentially could
prevent using a captured model as a whole.
[0211] Additionally, or alternatively, partially incomplete
three-dimensional captures can be used in viewing scenarios
providing six degrees of freedom with regard to movement of a
user's viewing position 16. This can significantly increase the
content that can be made compatible with six degree of freedom
viewing.
[0212] FIG. 6A illustrates an example of an apparatus 10. The
apparatus 10 may be a controller of an apparatus or electronic
device.
[0213] In examples, any suitable electronic device can be used, for
example electronic glasses or goggles, a headset, a mobile
telephone, a tablet device, a laptop, a desktop, a pda and so
on.
[0214] In examples, the apparatus 10 is configured and/or comprises
means for performing a method as described in relation to FIG. 1
and/or FIG. 2 and/or as described herein.
[0215] Implementation of an apparatus 10 may be as controller
circuitry. The apparatus 10 may be implemented in hardware alone,
have certain aspects in software including firmware alone or can be
a combination of hardware and software (including firmware).
[0216] As illustrated in FIG. 6A the apparatus 10 may be
implemented using instructions that enable hardware functionality,
for example, by using executable instructions of a computer program
26 in a general-purpose or special-purpose processor 22 that may be
stored on a computer readable storage medium (disk, memory etc) to
be executed by such a processor 22.
[0217] The processor 22 is configured to read from and write to the
memory 24. The processor 22 may also comprise an output interface
via which data and/or commands are output by the processor 22 and
an input interface via which data and/or commands are input to the
processor 22.
[0218] The memory 24 stores a computer program 26 comprising
computer program instructions (computer program code) that controls
the operation of the apparatus 10 when loaded into the processor
22. The computer program instructions, of the computer program 26,
provide the logic and routines that enables the apparatus 10 to
perform the methods illustrated in FIGS. 1 and/or 2 and/or as
described herein. The processor 22 by reading the memory 24 is able
to load and execute the computer program 26.
[0219] In examples the means comprises
[0220] at least one processor; and
[0221] at least one memory including computer program code, the at
least one memory and computer program code configured to, with the
at least one processor, cause the performance of the apparatus.
[0222] For example, the performance of a method as described
herein.
[0223] In examples, the apparatus 10 therefore comprises:
[0224] at least one processor 22; and
[0225] at least one memory 24 including computer program code
[0226] the at least one memory 24 and the computer program code
configured to, with the at least one processor 22, cause the
apparatus 10 at least to perform:
[0227] causing display of at least one world-locked volumetric
object having at least one non-viewable region; [0228] determining
a change in a user's viewing position relative to the at least one
world-locked volumetric object; [0229] determining if the change in
the user's viewing position relative to the at least one
world-locked volumetric object will cause display of at least a
portion of the at least one non-viewable region of the at least one
world-locked volumetric object; and [0230] if it is determined that
the change in the user's viewing position will cause display of at
least a portion of the at least one non-viewable region, causing
the at least one world-locked volumetric object to be
user-locked.
[0231] As illustrated in FIG. 6A, the computer program 26 may
arrive at the apparatus 10 via any suitable delivery mechanism 28.
The delivery mechanism 28 may be, for example, a machine readable
medium, a computer-readable medium, a non-transitory
computer-readable storage medium, a computer program product, a
memory device, a record medium such as a Compact Disc Read-Only
Memory (CD-ROM) or a Digital Versatile Disc (DVD) or a solid state
memory, an article of manufacture that comprises or tangibly
embodies the computer program 26. The delivery mechanism may be a
signal configured to reliably transfer the computer program 26. The
apparatus 10 may propagate or transmit the computer program 26 as a
computer data signal.
[0232] In examples, there is provided computer program instructions
for causing an apparatus to perform at least the following or for
performing at least the following:
[0233] determining a change in a user's viewing position relative
to the at least one world-locked volumetric object; [0234]
determining if the change in the user's viewing position relative
to the at least one world-locked volumetric object will cause
display of at least a portion of the at least one non-viewable
region of the at least one world-locked volumetric object; and
[0235] if it is determined that the change in the user's viewing
position will cause display of at least a portion of the at least
one non-viewable region, causing the at least one world-locked
volumetric object to be user-locked.
[0236] The computer program instructions may be comprised in a
computer program, a non-transitory computer readable medium, a
computer program product, a machine readable medium. In some but
not necessarily all examples, the computer program instructions may
be distributed over more than one computer program.
[0237] Although the memory 24 is illustrated as a single
component/circuitry it may be implemented as one or more separate
components/circuitry some or all of which may be
integrated/removable and/or may provide
permanent/semi-permanent/dynamic/cached storage.
[0238] In examples the memory 24 comprises a random access memory
30 and a read only memory 32. In examples the computer program 26
can be stored in the read only memory 32. See, for example, FIG.
6B
[0239] In some examples the memory 24 can be split into random
access memory 30 and read only memory 32.
[0240] Although the processor 22 is illustrated as a single
component/circuitry it may be implemented as one or more separate
components/circuitry some or all of which may be
integrated/removable. The processor 22 may be a single core or
multi-core processor.
[0241] References to `computer-readable storage medium`, `computer
program product`, `tangibly embodied computer program` etc. or a
`controller`, `computer`, `processor` etc. should be understood to
encompass not only computers having different architectures such as
single/multi-processor architectures and sequential (Von
Neumann)/parallel architectures but also specialized circuits such
as field-programmable gate arrays (FPGA), application specific
circuits (ASIC), signal processing devices and other processing
circuitry. References to computer program, instructions, code etc.
should be understood to encompass software for a programmable
processor or firmware such as, for example, the programmable
content of a hardware device whether instructions for a processor,
or configuration settings for a fixed-function device, gate array
or programmable logic device etc.
[0242] As used in this application, the term `circuitry` may refer
to one or more or all of the following:
[0243] (a) hardware-only circuitry implementations (such as
implementations in only analog and/or digital circuitry) and
[0244] (b) combinations of hardware circuits and software, such as
(as applicable):
[0245] (i) a combination of analog and/or digital hardware
circuit(s) with software/firmware and
[0246] (ii) any portions of hardware processor(s) with software
(including digital signal processor(s)), software, and memory(ies)
that work together to cause an apparatus, such as a mobile phone or
server, to perform various functions and
[0247] (c) hardware circuit(s) and or processor(s), such as a
microprocessor(s) or a portion of a microprocessor(s), that
requires software (for example, firmware) for operation, but the
software may not be present when it is not needed for
operation.
[0248] This definition of circuitry applies to all uses of this
term in this application, including in any claims. As a further
example, as used in this application, the term circuitry also
covers an implementation of merely a hardware circuit or processor
and its (or their) accompanying software and/or firmware.
[0249] The term circuitry also covers, for example and if
applicable to the particular claim element, a baseband integrated
circuit for a mobile device or a similar integrated circuit in a
server, a cellular network device, or other computing or network
device.
[0250] The blocks illustrated in the FIGS. 1 and/or 2 may represent
steps in a method and/or sections of code in the computer program
26. The illustration of a particular order to the blocks does not
necessarily imply that there is a required or preferred order for
the blocks and the order and arrangement of the block may be
varied. Furthermore, it may be possible for some blocks to be
omitted.
[0251] Where a structural feature has been described, it may be
replaced by means for performing one or more of the functions of
the structural feature whether that function or those functions are
explicitly or implicitly described.
[0252] Thus, the apparatus 10 can comprise means for:
[0253] causing display of at least one world-locked volumetric
object having at least one non-viewable region; [0254] determining
a change in a user's viewing position relative to the at least one
world-locked volumetric object; [0255] determining if the change in
the user's viewing position relative to the at least one
world-locked volumetric object will cause display of at least a
portion of the at least one non-viewable region of the at least one
world-locked volumetric object; and [0256] if it is determined that
the change in the user's viewing position will cause display of at
least a portion of the at least one non-viewable region, cause the
at least one world-locked volumetric object to be user-locked.
[0257] The above described examples find application as enabling
components of:
[0258] automotive systems; telecommunication systems; electronic
systems including consumer electronic products; distributed
computing systems; media systems for generating or rendering media
content including audio, visual and audio visual content and mixed,
mediated, virtual and/or augmented reality; personal systems
including personal health systems or personal fitness systems;
navigation systems; user interfaces also known as human machine
interfaces; networks including cellular, non-cellular, and optical
networks; ad-hoc networks; the internet; the internet of things;
virtualized networks; and/or related software and services.
[0259] The term `comprise` is used in this document with an
inclusive not an exclusive meaning. That is any reference to X
comprising Y indicates that X may comprise only one Y or may
comprise more than one Y. If it is intended to use `comprise` with
an exclusive meaning then it will be made clear in the context by
referring to "comprising only one . . . " or by using
"consisting".
[0260] In this description, reference has been made to various
examples. The description of features or functions in relation to
an example indicates that those features or functions are present
in that example. The use of the term `example` or `for example` or
`can` or `may` in the text denotes, whether explicitly stated or
not, that such features or functions are present in at least the
described example, whether described as an example or not, and that
they can be, but are not necessarily, present in some of or all
other examples. Thus `example`, `for example`, `can` or `may`
refers to a particular instance in a class of examples. A property
of the instance can be a property of only that instance or a
property of the class or a property of a sub-class of the class
that includes some but not all of the instances in the class. It is
therefore implicitly disclosed that a feature described with
reference to one example but not with reference to another example,
can where possible be used in that other example as part of a
working combination but does not necessarily have to be used in
that other example.
[0261] Although examples have been described in the preceding
paragraphs with reference to various examples, it should be
appreciated that modifications to the examples given can be made
without departing from the scope of the claims.
[0262] Features described in the preceding description may be used
in combinations other than the combinations explicitly described
above.
[0263] Although functions have been described with reference to
certain features, those functions may be performable by other
features whether described or not.
[0264] Although features have been described with reference to
certain examples, those features may also be present in other
examples whether described or not.
[0265] The term `a` or `the` is used in this document with an
inclusive not an exclusive meaning. That is any reference to X
comprising a/the Y indicates that X may comprise only one Y or may
comprise more than one Y unless the context clearly indicates the
contrary. If it is intended to use `a` or `the` with an exclusive
meaning then it will be made clear in the context. In some
circumstances the use of `at least one` or `one or more` may be
used to emphasis an inclusive meaning but the absence of these
terms should not be taken to infer any exclusive meaning.
[0266] The presence of a feature (or combination of features) in a
claim is a reference to that feature or (combination of features)
itself and also to features that achieve substantially the same
technical effect (equivalent features). The equivalent features
include, for example, features that are variants and achieve
substantially the same result in substantially the same way. The
equivalent features include, for example, features that perform
substantially the same function, in substantially the same way to
achieve substantially the same result.
[0267] In this description, reference has been made to various
examples using adjectives or adjectival phrases to describe
characteristics of the examples. Such a description of a
characteristic in relation to an example indicates that the
characteristic is present in some examples exactly as described and
is present in other examples substantially as described.
[0268] Whilst endeavoring in the foregoing specification to draw
attention to those features believed to be of importance it should
be understood that the Applicant may seek protection via the claims
in respect of any patentable feature or combination of features
hereinbefore referred to and/or shown in the drawings whether or
not emphasis has been placed thereon.
